I was forgetting that my dev environment is also in Docker so I didn't really need to care about the poetry environment.

Instead, you can add a requirement on a non-existent version while replacing that version:

The immediate reason for this happening is because reloadfx.Play (); is being called for every frame that your reloading is occurring. That means it's getting restarted over and over, until finally your reload finishes and it can play in its entirety.
